Electrical specifications do not apply when operating the device outside of its stated operating conditions. Note 2:All limits are guaranteed at either room temperature (standard type face) or attemperature extremes (bold typeface)by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Note 3:Unless otherwise specified: |VIN −V OUT |= 5V, IOUT = 0.5A, PDISS ≤ 30W. Note 4:Load and line regulation are measured at constant junction temperature, using low duty cycle pulse testing (output voltage changes due to heating effects are covered by the Thermal Regulation specification). For the TO-3 package, load regulation is measured on the output pin,1⁄8" below the base of the package. Note 5:The output current of the LM333 is guaranteed to be≥ 3A in the range 3V≤ |VIN −V OUT |≤ 10V. For the range 10V≤ |VIN −V OUT |≤ 15V, the guaranteed minimum output current is equal to: 30/ (VIN −V OUT ). Refer to graphs for guaranteed output currents at other voltages. www.national.com3

Adjustable Negative Voltage Regulator DS009065-3 †C1 = 1 µF solid tantalum or 10 µF aluminum electrolytic required for stability. *C2 = 1 µF solid tantalum is required only if regulator is more than 4" from power supply filter capacitor. Output capacitors in the range of 1 µF to 1000 µF of aluminum or tantalum electrolytic are commonly used to provide lower output impedance and improved transient response. www.national.com 8
